Rusty_OToole Posted June 12, 2023 Share Posted June 12, 2023 (edited) Buick made 3 models that year Buick Special - 40 series -248 cu in 115HP manual trans, 124HP Dynaflow trans. The engine used in Dynaflow models had higher compression Buick Super - 50 series - 263.3 cu in 124HP manual, 128HP Dynaflow Roadmaster - 70 series - 320 cu in 152HP If you want to know exactly what engine you have you will need to find the serial number stamped into the engine block. Stamped on a raised boss on the right side of the engine below the push rod cover. The number is located near the front of the motor - ahead of the distributor on 40 & 50 series, near the rear of the engine on 70 series.

punisher Posted June 12, 2023 Author Share Posted June 12, 2023 Are the seals identical on all Dynaflow automatic gearboxes? I think this cover is good but I'm not sure https://bobsautomobilia.com/shop/rr-axle-housing/transmission-shifter-parts/dynaflow-paperrubber-seal-kit-1948-52-dsk-482/ Link to comment Share on other sites More sharing options...
Rusty_OToole Posted June 12, 2023 Share Posted June 12, 2023 (edited) The advertisement says "need year and series when ordering" so I would give him that information. Your car should have an emblem that says Special, Super or Roadmaster. Or the serial number or body number should identify it as a 40, 50 or 70 series. Look on the firewall for a identification plate. And look for the engine serial number.
